I am a failure.

Don’t be so hard on yourself. Lding will be more difficult with that sort of thinking. I think you should a.)don’t try so hard b.)change your attitude and c.) give LucidWarp a try. It helped me a lot. If you do decide to use LucidWarp, follow the instructions and do one day at a time. I wish you best of luck!
